Improved horse-power



UNITED STATES PATENT OEEIC.

J. M. RANDLE, OF BRIGHTON, ILLINOIS, ASSIGNOR TO HIMSELF AND J. W. HILL,OF SAME PLAGE.

IMPROVED HORSE-POWER.

Specification forming part of Letters Patent No. 53,378, dated March 20,1866.

To all whom 'it may concern:

Be it known that I, J. M. RANDLE, of

` Brighton, in the county otMacoupin and State of Illinois, haveinvented a new and useful Improvement in Horse-Powers t'or Hay-Derricksor other similar uses; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

Figure l of the annexed drawings is a perspective view of one of theimproved horsepowers. Fig. 2 is a plan ofthe same. Fig.3 is a transversevertical section ot` the machine through its axis, and Fig. et is asectional elevation ot` the clutch-post which forms the journal for therim-wheel.

This invention consists in making a horsepower in such a manner that itcan be unshipped by a man at some distance from itfor instance, on topot' a load ot hay in the case ot' a hay-derrick.

A Vis a foundation frame-work, upon which the other parts are erected. Bisa vertical journal erected upon A, upon which the metallic hub O restsand around which it revolves.

C is a horizontal wheel rmly attached to the hub C, and provided with aflange, c, around the lower edge of its periphery, to keep thedraft-rope D from ruiming oft at the bottom.

E is a vertical post, in the lower end ot' which is a cylindricalcavity, with the threads of a female screw cut therein that fit thescrew-threads e on the upper end ot' the journal B.

E is a ring, with clutch-joints d on the lower end of it, that lit intothe clutch-joints d on the upper end of the hub O when all the parts aretogether and in operation. rlhe clutchring E is placed on the lower endof the post E in such a manner that it may receive a slight verticalmotion sufficient to raise the clutches I out of the clutches d.

The curved metallic arm E3, projecting from 011e side of the postgE nearits lower end, furnishes atV orV a fulcrum for the lever E2, which isconnected with the clutch-ring E by means of two pins, that enteri agroove made around the periphery of the clutch-ring, so that said ringmay revolve around the post E without the pins x stopping its rotarymotion.

A cord, E, is fastened to the lever E2 near its outer end, from whichpoint ot' attachment it passes up in a diagonal direction to a mortisemade for its passage through the top end of the post E, and from thenceit passes on to the location of the operator, which, in the case of ahay-derrick, will be on top of the load of hay.

When the operator draws up the cord E4 it will raise the long arm ot'the lever E2 high enough for the pins x to elevate the ring Esufficiently to allow the clutches d to become disconnected from theclutches d', thereby affording a very economical and effective shippingand unshipping arrangement tor that 'class ot' horse-powers which aresuitable for hay-derricks.

Au iron arm, G2, has an annular end which surrounds the upper end of thehub C, and there are clutch-openings d', similar to those in the upperend ot' the hub C, made in the upper part of this annular end.

When the clutches d are down they enter the clutches d in both the leverC2 and the hub C, and so couple all these parts together.

The motive power is to be attached to the outer end of the lever O3, theinner end of which is trmly secured to the arm C2.

One end of the draft-rope D is trmly fastened to the periphery of thewheel C', from which point the other end is conducted out through thetimber-head A', where it should pass over a sheave, (not shown,) andthen be attached to the wei ght to be raised.

The machine, constructed as above described, and the horses attached tothe outer end ot' the lever C3, when the team has turned the wheel O farenough around to take up a sufficiency of the rope D to raise the Weight(not shown) attached to its outer end to the required elevation, theoperator will draw the cord E, which will, as has been shown, disconnecttlic clutches d and d', and so stop the motion of the (.lrat't-rope Dinstantly, although the team may continue to advance.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

The combination of the wheel C', arm C2, lever O3, and journal B withthe post E, clutch-ring E', lever E2, and ropes D and E4, whenconstructed and arranged as and for the purpose set forth.
